Radiator cap

A reliable seal for the cooling system The cap on the expansion tank is a small but important part for engine performance. It maintains the correct pressure in the cooling system, which raises the boiling point of the coolant. Due to constant exposure to heat and pressure, the plastic of the cap can become brittle and its seals can harden over time, leading to overheating and engine damage in trucks and tractors. Caps for expansion tanks and radiators febi supplies replacement parts that are a precise fit for the original connection. The range includes the most common caps for coolant expansion tanks, as well as specific radiator caps and bolt plugs. This allows mechanics to fix leaks quickly and properly, preventing major problems with a minor intervention during regular maintenance.
